本文以研究懸索橋受地震力作用後的動力歷時反應，並對懸索橋受力作用後的安全狀態進行破壞判定，使用的方法為向量式有限元素法，分析模型為碧潭吊橋模型，此模型是以光達掃描現況幾何後於sap2000建模在於VFIFE進行分析，以溫度與人數的監測資料調整模型，並於地震力與風力加載之後進行碧潭吊橋可能發生破壞的位置進行檢核，例如主纜索描定塊、鎢球軸承處、橋柱、鞍座等位置。;This paper studies the dynamic response of the Suspension bridge after the earthquake force. Suspension bridge is Flexible structure. Determining the security status of suspension by force after the destruction failure. And using VFIFE to analyze the dynamic response. In this case, Bitan Suspension bridge is used. By using data of temperature and human being to build the model. And apply external forces into model to determining structure failure.
